Evolution is always revolutionary to those caught up in it. Only hindsight makes a revolution part of an ongoing evolution.
If you're not part of the revolution, you won't evolve. If you don't evolve, you're stuck in a dead end of ever-decreasing resources.
Of course, this is to confuse the individual and the tribe.
An alternate way of putting this - no individual survives (Darwinian) evolution. Thank goodness culture is Lamarckian.
